Cast iron graphite

The formation process of graphite in cast iron is called graphization process. The basic process formed by cast iron tissue is the formation of graphite in cast iron.The graphite type and size of the gray cast iron depends on the graphite branches and growth rate in the common crystal group. When the common crystal group stops growing, the graphite will stop. They are separated and not connected. Using scanning electron microscope to observe the complete graphite in the common crystal groupThe three -dimensional form indicates that they are connected to each other. Only on the gold phase grinding surface is isolated.The national standard has the following divisions of the graphics of cast iron graphite: type A fine sheet, B -shaped flower shape, C -shaped thick blockbuster, D -shaped dot, E has directional points, f spider -like or planetary. The longest (100 times, greater than 100mm is 100mm. It is called 100mm long). The shortest graphite is the shortest (100 times at 100 times, le

Graph

Floating method is a type with less energy consumption and reagent consumption and low cost in the conventional purification method of minerals. Real limited improvement. For scales graphite, multi -segment grinding ore cannot be completely unbuttoned, but it is not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite quality. High carbide graphite with more than 99%must be pure graphite with chemical methods.(1) chloride roasting methodThe low roasting temperature and smaller chlorine gas consumption of chloride roasting method have greatly reduced the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to the treatment of hydrofluoric acid method. Compared with the recovery rate of chloride and roasting method, because the chlorine gas is poisonous and has strong corrosiveness, it requires high requirements for equipment operations. It requires strict requirements. Seal

The difference and connection between graphite and graphene

The main difference between graphite and graphene lies in their structure. Graphite is a two-dimensional material with a hexagonal lattice formed by carbon atoms, and is an allotrope of carbon. And graphene is a type of material composed of carbon atoms in the form of sp ² A two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of hybrid orbitals is a single-layer structure of graphite. Therefore, graphite can be seen as a stacked form of graphene.Graphene has some unique physical and chemical properties, such as excellent conductivity and thermal conductivity, high strength, high toughness, etc., making it have broad application prospects in energy, materials, electronics and other fields. Due to its structure, graphite mainly has excellent lubrication and wear resistance, and is commonly used in the manufacturing of lubricants and wear-resistant materials.Although there are significant differences in structure and properties between graphite and graphene, t
